Introducing uncertainty of radar-rainfall estimates to the verification of mesoscale model precipitation forecasts
radar-rainfall estimates mesoscale model precipitation forecasts
2009/12/30
A simple measure of the uncertainty associated with using radar-derived rainfall estimates as "truth" has been introduced to the Numerical Weather Prediction (NWP) verification process to assess the e...
Radar rainfall estimates in an alpine environment using inverse hydrological modelling
Radar rainfall an alpine environment inverse hydrological modelling
2010/1/26
The quality of hydrological modelling is limited due to the restricted availability of high resolution temporal and spatial input data such as temperature, global radiation, and precipitation. Radar-b...
Multifractal analysis of radar rainfall fields over the area of Rome
Multifractal analysis radar rainfall fields the area of Rome
2010/1/22
A scale-invariance analysis of space and time rainfall events monitored by meteorological radar over the area of Rome (Italy) is proposed. The study of the scale-invariance properties of intense preci...
Reconstruction of reflectivity vertical profiles and data quality control for C-band radar rainfall estimation
reflectivity vertical profiles data quality control C-band radar rainfall estimation
2010/1/22
Microwave Doppler radars are considered a fairly established technique to retrieve rain rate fields from measured reflectivity volumes. However, in a complex orographic environment radar observations ...
Improved radar rainfall estimation at ground level
radar rainfall estimation ground level
2009/12/29
A technique has been developed to provide an estimate of the rainfall reaching the earth's surface by extrapolating radar data contained aloft to ground level, simultaneously estimating unknown data i...
Model-based iterative approach to polarimetric radar rainfall estimation in presence of path attenuation
Model-based iterative approach polarimetric radar rainfall estimation path attenuation
2010/1/22
A new model-based iterative technique to correct for attenuation and differential attenuation and retrieve rain rate, based on a neural-network scheme and a differential phase constraint, is presented...
